"Ett liv i två världar" : En kvalitativ studie om hur pojkar konstruerar etnisk och religiös identitet i olika sociala kontexter
"One life in two worlds" is a qualitative study of Syriac boys constructs ethnic and religious identity in different social contexts.Based on these three questions: how do the boys describe the importance of the parents' cultural and religious background in relation to their own identity? How do the boys describe their experiences of being categorized in school? Which significance is given to religion and ethnicity when the boys describe their experiences in relation to home and school context?I did reach the aim of this essay which was to investigate by interviewing the Syrian boys how they construct or reconstruct ethnic and / or religious identity in relation to different social contexts with a focus on the home and the school.In this study, I assumed the qualitative method in which I interviewed six Syriac boys who attend grade nine. The starting point of the study was social constructivism. Therefore, knowledge in this study is seen as something that is constructed in language, social and cultural interactions. The reality and perspective of reality is socially constructed, meaning that knowledge is created through the interplay of common action.The results of this study show that all the informants are agreed that their parents' ethnic background has had and has great significance for their identity formation.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal
This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.
Den moderna matnörden
Det finns många aspekter som påverkar människors matval. Smak och preferenser är endast några av flera aspekter som styr vad vi äter. Kultur, samhälle, familj, vänner och ekonomi är några av de saker som spelar in när vi väljer mat. Därmed medför själva matvalet en identi- tetsaspekt, vi är helt enkelt vad vi äter. Idag har vi via sociala medier stora möjligheter att dela med oss av våra åsikter och visa glimtar av vår tillvaro för vår omgivning och mat är ett van- ligt återkommande ämne i blogginlägg och ett motiv för bilder.
Kalciums och magnesiums inverkan på arsenikavdrivningen i virvelbäddsugnen : The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace
In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.

Lakningsförsök med furubarksflis : en utredning om utsläpp av fenolföreningar samt metallsorption
The filters used today to purify water are often expensive and the need to find new filter materials is substantial. Studies of pine bark have shown that this is a material that may be used as an alternative to conventional filter materials, such as activated carbon. However, the study of pine bark has shown that a leakage of phenolic compounds may occur when using the material for water purification. Therefore, the purpose of this report is to investigate the release of phenols from pine bark, in order to evaluate the use of pine bark as a filter material. Another assignment is to investigate the amount of metals adsorbed by the filter material.

Koldiffusionens inverkan på utmattnings-hållfastheten hos varmvalsade sexkantsstänger;The influence of carbon diffusion on the fatigue strength of hot rolled hexagonal rods
Helstångsborr och konstång kallas bergborrverktyg, som tillverkas av sexkantiga stänger med inre hål för ledning av spolvatten. Dessa spolhål är klädda med ferritiskt rostfritt stål. Innan valsning borras ett centrerat hål i stålämnet som ska valsas. I det borrade hålet appliceras ett rör av ferritiskt rostfritt stål och i det röret skjuts en manganstålskärna in. Efter valsning dras kärnan ut och ett spolhål med invändigt foder av rostfritt stål bildas.
Livscykelanalys och optimering av isoleringstjocklek för moderna byggnader : - med fokus på kv Limnologen i Växjö
Syftet med denna rapport är att visa hur en ökning av isolertjockleken i ett hus påverkar kostnader och energiåtgång för isoleringen i ett livscykelperspektiv, samt för husets bruksskede. I studien har en optimering av isoleringen på ett pågående byggprojekt i Växjö, kv Limnologen, utförts. Total energiåtgång för isoleringens livscykel har tagits fram från tidigare utförda livscykelanalyser (LCA). Husets värmebehov har beräknats mha information från ritningar och kontakter med personer i anknytning till kv Limnologen. En ekvation har utformats för att finna ett teoretiskt optimum för isolertjockleken med inriktning mot total energiåtgång, koldioxidutsläpp och ekonomi.
Ägarlägenhetsförrättningar ur ett kostnadsperspektiv : Hur utvalda faktorer påverkar förrättningskostnaden och den framtida förvaltningen
The purpose of this study is to get the cadastral procedure for condominiums to become more affordable. The aims of the study is to examine how the number of condominiums, the number of joint facilities and the number of joint property units that are formed in a condominium cadastral procedure in Sweden influences the cadastral procedure cost. To get an overall perspective the study also explores how the chosen forms of co-operation have worked out in association management.A condominium is a type of three-dimensional property unit, which may only contain one residence. This form of property formation has been allowed in Sweden since 1 May 2009. At the end of 2014 less than 1000 condominiums had been formed despite the legislator?s expectations for 3000-5000 condominiums a year. The property unit can have access to necessary facilities, not available within the property boundaries, by establishing joint facilities or form joint property units.
Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)
Peat lands are a great potential resource for increased forest growth in Sweden, there are approximately 6.5 million hectares of peat lands, whereof around 70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste land. There are over 200 000 hectares of peat land that is already drained and wooded, and that may be suitable for fertilization. Forest production on peat soils usually requires drainage and fertilization. Dewatering requires ditching the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The purpose of this work was to examine the effects of potassium fertilization on the growth of spruces that were planted on drained peat land and how different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance transport in the tree. Potassium is also important for the carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter resistance of many species. Potassium is not found in any organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was left without fertilization. All plots that were fertilized with potassium grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality estimation of wetlands after ditching (dikningsbonitering). The plot with most potassium produced after fertilizationaproximately in level with theoretical estimations. Key words: Peat land, Fertilization, Ditching, Growth, site quality..
Anestesi av det neonatala fölet
Every spring you can see newborn foals running on fields among the mare. But some unfortunate end up visiting the equine hospital requiring surgery. This is a challenge for the anesthetist because of the neonatal foal?s unique physiology. Therefore you need to take these differences under consideration when you anesthetize foals.
Hur b?rjar man leva n?r man ?r redo att d?? En kvalitativ studie om m?nniskor som l?mnat Jehovas vittnen
The aim of this study was to create a greater understanding of apostates, by analyzing narratives of five ex-members regarding their exit from Jehovah?s Witnesses. I conducted interviews to gather descriptions from specific individuals in relation to their experiences, mainly focusing on the role of an ex-member of a specific group. The informants in the study were 38-73 years old, three women and two men. The empirical data I collected was later coded through qualitative content analysis, where central topics and themes formed the basis for the analysis of the results.
Solel från ljudbarriär : längs Annetorpsvägen i Hyllie, Malmö
City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.
